"Lithium-Ion Charged Polymer Channels Flattening Lithium Metal Anode" by Haofan Duan, Yu You et al.

The concentration difference in the near-surface region of lithium metal is the main cause of lithium dendrite growth. Resolving this issue will be key to achieving high-performance lithium metal batteries (LMBs). Herein, we construct a lithium nitrate (LiNO3)-implanted electroactive β phase polyvinylidene fluoride-co-hexafluoropropylene (PVDF-HFP) crystalline polymorph layer (PHL). The electronegatively charged polymer chains attain lithium ions on the surface to form lithium-ion charged channels. These channels act as reservoirs to sustainably release Li ions to recompense the ionic flux of electrolytes, decreasing the growth of lithium dendrites. The stretched molecular channels can also accelerate the transport of Li ions. The combined effects enable a high Coulombic efficiency of 97.0% for 250 cycles in lithium (Li)||copper (Cu) cell and a stable symmetric plating/stripping behavior over 2000 h at 3 mA cm−2 with ultrahigh Li utilization of 50%. Furthermore, the full cell couple ....

"Enhanced lithiophilicity via bismuth-infused framework for advanced li" by Joo Hyeong Suh, Hamzeh Qutaish et al.

Utilizing carbon materials as 3D lithium (Li) hosts hold a significant interest in constructing high-energy batteries. However, there are ongoing challenges associated with these frameworks owing to their poor Li affinity. Recent advancements, including alloying reactions with precious metals like silver (Ag) and gold (Au), have emerged as a promising technique to enhance the electrochemical performance of these host materials. Nevertheless, the search for cost-effective alternatives remains a pressing demand. Herein, this work employed galvanic displacement (GD) to integrate bismuth into disordered porous carbon (Bi-DPC) and optimized across different concentrations (0.01, 0.05, 0.1 M). As a result, the Li deposition onto the Bi-DPC surface exhibited dendrite-free planar morphologies, revealing an outstanding electrochemical performance, including a high CE of around 100 % over more than 100 cycles. These findings underscore the potential of Bi-infused porous carbon as a promising alt ....
